🧒

I’ve got a cold — my throat hurts a lot and I have a light fever. Would Pabron Ace Pro-X be a good choice?

👩‍⚕️

Yes. It fits colds where sore throat + fever are prominent. Ibuprofen reduces pain/fever; Ambroxol + L-carbocisteine help your airway mucus and phlegm; Pseudoephedrine eases nasal stuffiness; Chlorpheniramine calms sneezing/runny nose; and Dihydrocodeine suppresses cough. In short, 7 ingredients cover multiple symptoms.

🧒

How should I take it? Will it make me sleepy? Is driving OK?

👩‍⚕️

Ages 15 and over: take 3 tablets per dose, 3 times daily, preferably within 30 minutes after meals. Do not use under 15.
Because it contains an antihistamine, it may cause drowsiness. Do not drive or operate machinery after taking it. Limit use to no longer than 5 days. If not improving, see a doctor.

🧒

What about pregnancy or breastfeeding?

👩‍⚕️

Do not use in the late stage of pregnancy (within 12 weeks before the due date).
If you’re breastfeeding, avoid use or avoid nursing while taking it. When in doubt, consult your doctor or pharmacist first.

🧒

I’m already on allergy meds. Can I combine them?

👩‍⚕️

Avoid combining with other cold medicines, pain/fever reducers, cough & phlegm meds, or antihistamines (risk of duplicate ingredients). If you take an MAO inhibitor, ask your doctor first. Also do not drink alcohol while using this.
